リート躯体の底面に柔軟性材料からなる摩擦部材を取り
付けて摩擦係数を増大させることが行なわれている。(Prior art) In order to prevent sliding due to external force such as wave force, gravity type structures such as caisson used for construction of breakwaters, quays, etc. are equipped with a friction member made of a flexible material on the bottom of the concrete skeleton to prevent friction. Increasing the coefficient is being done.
柔軟性材料としては、通常、天然ゴム、合成ゴムの他

等の底面に取り付けた摩擦部材により摩擦係数を増大さ
せ、波力等の外力による滑動を防止している。Conventionally, for the construction of breakwaters, etc., the seabed is dug out, and rubble stones are piled on it to create a mixed foundation rubble mound, and an asphalt mat is laid on this mound to sink caisson, etc. Complete by sinking the attached caisson. A friction member attached to the bottom surface of the asphalt mat or caisson increases the friction coefficient to prevent sliding due to external force such as wave force.
（考案が解決しようとする課題） ところが、アスファルトマットは、広い保管場所を必要
とし、その敷設にも気象条件等による制約を受けるとい
う問題がある。(Problems to be solved by the invention) However, the asphalt mat requires a large storage space, and there is a problem that its installation is also restricted by weather conditions and the like.

させればそれだけコストアップとなる。That is, in order to install caisson etc. more stably, if a concrete mound is used instead of the conventional mixed foundation rubble mound, if a friction member is projected to the bottom of the gravity type structure, concentrated load will be applied to that part. Therefore, the strength of the concrete frame must be increased. If the strength is increased, the cost is increased accordingly.

構造物を提供しようとするものである。The present invention has been made in view of the above problems of the conventional technology, and the purpose thereof is to install a friction member on the bottom surface and install it on a smooth foundation surface such as a concrete mound. It is intended to provide a gravity type structure without a concentrated load.
（課題を解決するための手段） この考案は上記目的を達成するために、次のような構成

一面となる大きさであることを特徴とするものである。That is, in a gravity type structure with a friction member attached to the bottom surface, in a gravity type structure with a friction member attached to the bottom surface, a friction member formed of an elastic body in a groove and / or a recess provided in the bottom surface protrudes from the bottom surface. And a gap is formed on all or part of the side surface of the friction member with the side surface of the groove and / or the recess, and the gap is formed by compression of the friction member when installed on the base surface. It is characterized in that the deformed portion is accommodated and the bottom surface of the friction member and the bottom surface of the gravity type structure are flush with each other.

く。(Function) Since the friction member is formed higher than the depth of the groove or the recess, when the gravity type structure is installed on the foundation surface, the friction member is compressed, but the gap between the groove and the side wall of the recess is formed by the friction member. Since it acts as a clearance place for the friction member, the entire friction member is buried and no concentrated load is applied. Since the friction member has a repulsive force and presses the foundation surface, it moves so as to prevent the gravity type structure from sliding.

に、圧縮変形部分を収納する大きさに形成されている。The friction member 5 is formed according to the shapes of the groove 7 and the recess 9 to be attached, but its cross-sectional shape may be round or square, and its size may be the flexibility of the friction member.
It is appropriately determined according to the size of the concrete skeleton 1, and projects below the bottom surface 3 of the concrete skeleton 1.
In this invention, the friction member 5 is compressed so as to be flush with the bottom surface 3 of the concrete skeleton 1 when installed on a concrete mound or the like. That is, the gap 11 is provided between the groove 7 and the side surface of the recess 9 on all or part of the side surface of the friction member 5. The space 11 serves as an escape area for the deformed portion when the friction member 5 is compressed, and is formed in a size to accommodate the compressed deformed portion so that the bottom surface of the friction member 5 is flush with the bottom surface 3 of the concrete skeleton 1. ing.

重は底面３全体で受けることになり、摩擦部材５の部分
には集中荷重はかからない。Since the friction member 5 is an elastic body having a repulsive force, it presses the concrete mound or the like even when it is compressed, and as a friction member, it prevents sliding of the concrete skeleton. Therefore, it is desirable that the gap 11 is provided over the entire side surface of the friction member 5. When the friction member 5 is housed in the groove 7 and the recess 9 when compressed and becomes flush with the bottom surface 3 of the concrete skeleton 1, the load of the concrete skeleton 1 is received by the entire bottom surface 3, and the friction member 5 No concentrated load is applied to the part.

ようにしてもよい。In the above-mentioned configuration, in order to provide the friction member 5, the groove 7 and / or the recess 9 is formed on the bottom surface 3 of the concrete skeleton 1 by an appropriate method, and then the separately formed friction member 5 is embedded or the separately formed friction member is formed. The member 5 may be used as a part of the bottom surface of the form, and may be provided by pouring concrete.
尚、実施例ではケーソンに適用した場合を示したが、こ
れに限らずその他のコンクリート躯体に取り付ける場合
にも有効に適用し得る。In addition, although the case where it applied to a caisson was shown in the Example, it is not limited to this and it can be applied effectively also when it is attached to another concrete frame.
以上、本実施例によると以下のような効果を奏すること
ができる。As described above, according to this embodiment, the following effects can be obtained.
摩擦部材はコンクリート躯体の底面よりも突出している
が、基礎面に設置されると圧縮され間隙に逃げ込むの
で、集中荷重がかからないとともに、コンクリート躯体
の底面は基礎面に当接し、安定した設置ができる。The friction member protrudes from the bottom surface of the concrete structure, but when it is installed on the foundation surface it is compressed and escapes into the gap, so no concentrated load is applied and the bottom surface of the concrete structure abuts the foundation surface for stable installation. .
摩擦部材は単に溝または凹部内に埋設するだけであるか
ら、取り付けが簡単である。Since the friction member is simply embedded in the groove or the recess, it is easy to install.
埋設部材は溝または凹部内に設けられているので、安定
して取り付けられるとともに、摩擦係数を高めることが
できる。Since the embedded member is provided in the groove or the concave portion, it can be stably attached and the friction coefficient can be increased.

きる。(Effect of the Invention) As described above, according to the present invention, even if the gravity type structure is installed on a smooth foundation surface such as a concrete mound, the concentrated load by the friction member is not received.
The strength of the gravity type structure will not be increased more than necessary. Therefore, the cost can be reduced as a whole.
重力式構造物の底面を基礎面に当接させることにより、
弾性体である摩擦部材の反発力により常に基礎面を押圧
